CURVED SHADE-ROLLER AND CURTAIN-ROD.

To all whom it may concern:

Be it known that I, ISHMAEL F. HURLBUT, a citizen of the United States,and a resident of the city and county of San Francisco and State ofCalifornia, have invented a new and useful Improvement in CurvedShadedtollers and Curtain-Rods, of which the following is aspecification.

My invention relates to curved shade rollers and curtain rods whereinparallel rods are suitably supported by means of end brackets and theinner rod, or that rod nearest the window, is provided with a pluralityof rotatable telescoping sections connected to each other at one pointonly, and are supported upon the said inner rod, and wherein a coiledspring is adapted to rotate the tele' scoping sections for the purposeof rolling or unrolling the shade upon the roller. I also employ novelmeans on the same brackets for the support of a curved curtain rod uponwhich may be hung the lace or other curtains which are usually providedinside of the shade, and the objects of my invention are, first, toprovide a curved shade roller which is adapted to hold a shade suspendedin a curve parallel with the curved window near which it is attached,second, to provide a flexible tube which is adapted to rotate upon andreadily conform to the curve of a stationary curved supporting rod,third, to provide means for readily rewinding a shade upon the roller,fourth, to provide a simple and substantial connection between eachsection of the flexible tube, novel and practical means for the supportof a curved curtain rod so that the said curtain rod shall be maintainedin a horizontal plane.

For a full and clear comprehension of my invention, reference should behad to the drawings forming a part of this specification, wherein likenumerals of reference designate similar parts throughout the saidspecification and drawings and in which- Figure 1 is a broken plan viewof the curved shade roller disclosing the telescoping sections rotatablymounted upon the stationary supporting rod. F ig. 2 is a broken detailedview of one end of the flexible tube, disclosing the manner in which therotating spring is wound upon the rod and connected at one end to theend section. Fig. 3 is an end view, on an enlarged scale, of Fig. 2,disclosing the manner in which the pawls are secured to the end sectionSpecification of Letters Patent.

and engage the stationary supporting rod.

Fig. 4: is an end View, on an enlarged scale, of the bracket and theflexible tube, also showing the manner in which the curved curtain rodis secured to the end of the bracket. Fig. 5 is a detailed broken viewof one end of the curtain rod disclosing the manner in which the end ofthe bracket engages the end of the said curtain rod.

My invention consists substantially of suitable supporting brackets 1having slots 2 adapted to engage and hold against rotation the ends ofthe curved inner parallel rod 3. Hollow telescoping sections 5 arepivotally secured to each other at one point only as at 6 and areadapted to rotate around the stationary rods 3. Each of the end sections5 are provided with the circular, flanged end plate 7 to which arepivotally secured the pawls 8 adapted to engage the squared portions 3of the rod 3. A disk 10 is rigidly secured to the center of the rod 3and to this disk 10 is secured the center of a coil spring 9, theopposite ends of the said spring9 being rigidly secured to the endplates 7. The brackets 1 are provided with offset extensions 12 at theouter ends thereof, the said extensions 12 being adapted to engage,support and held against rotation the curved parallel curtain rod 1 1 bymeans of the slot 15 which is provided in the lower surface of each endof the said rod 14. (See Fig. 5 of the drawings.) In this manner thecurved curtain rod is supported and held against rotation for the reasonthat the greater part of the curved rod is inside of an imaginary linedrawn between the extensions 12 of both brackets. As the tendency of thecurved rod would be to rotate until the center thereof rested at a pointbelow the points of support, the edge of the slot 15 which is below theextension 19. would tend to move upward. As this tendency of the loweredge of the slot to move upward is checked by the extension 12, it isapparent that the curved curtain rod 14E will be held so that the curvethereof is always in a horizontal plane.

The operation of the curtain roller is as follows: The inner parallelrod 3 is held against rotation by means of the slots 2 in the brackets 1and acts as a support to the rotatable telescoping sections 5 thereon.The shade is secured in any suitable manner to the outer surfaces of thetelescoping sections 5. By pulling downwardly, the shade will cause thetelescoping sections 5 to rotate against the tension of the spring 9which is secured to the said sections 5 and to the inner parallel rod 3.Then the shade is released, the tension of the spring 9 will cause thesections 5 to rotate in the opposite direction and thereby wind up theshade. As the combined sections 5 rotate they readily conform to thecurvature of the inner parallel rod 3 for the reason that each section 5is pivotally seclured to the succeeding section at one point on y.

I am aware that telescoping sections have been heretofore employedwherein the said sections were pivotally connected to each other ondiametrically opposed points in their adjacent peripheries and thecombined sections inclosed by means of a flexible covering. But theflexibility of such an arrangement has been proved in practice to beinsufficient for the reason that two adj oining sections could only turnon one axis and the consequent friction of the flexible covering wasalso adapted to resist a free conformity to the curvature of thesupporting rod. In my device I have provided connection of the sectionsat one point only so as to insure an easy and free movement between thesections. In this manner my device is adapted to readily and freelyadapt itself to the curvature of the inner sup-porting rod in anyposition.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is 1. A curved shade roller and curtain rodcomprising curved parallel rods; means for supporting the parallel rodsabove a window casement; telescoping sections rotatably mounted upon theinner parallel curved rod and connected to each other at one point intheir adjacent peripheries; and a coil spring secured to the innerparallel rod and adapted to rotate the telescoping sections in onedirection.

2. A curved shade roller and curtain rod comprising curved parallelrods; suitable brackets adapted to engage the ends of the parallel rodsand to support the same .above a window casing; telescoping sectionsrotatably mounted upon the inner parallel curved rod and connected toeach other at one point in their adjacent peripheries; a coil springsecured at both ends to the end telescoping sections, the center of thesaid spring being secured to the inner parallel rod; and means forretaining the telescoping sections against rotation.

3. In a curved shade roller and curtain rod, the combination of suitablebrackets, each bracket having a slot in the upper edge and an oifsetextension on the outer end thereof; an inner curved rod adapted to berigidly held within the slots of the brackets and having a squaredportion near the outer ends thereofand within the brackets; an outercurved rod having slots in the under surfaces at the outer ends thereofsaid slots being engaged by the offset extensions of the brackets;telescoping sections rotatably mounted upon the inner curved rod andpivotally connected to each other at one point in their adjacentperipheries; a disk set within the outer end of each outer section; andpawls pivotally secured to each disk and adapted to engage the squaredportions of the inner rod and prevent the rotation of the telescopingsections when the said sections are rotated slowly.

In witness whereof I hereunto set my signature in the presence of twosubscribing witnesses.
